What's the difference between a flood and a flash flood? Flash floods are distinguished from a regular flood by the length of time it takes for the flood to occur. Under six hours, the flood is referred to as a flash flood. Some can occur within minutes. Areas will not always be able receive a warning that these floods are coming and people can be caught off-guard.
Flash floods can occur under several types of conditions. Flash flooding occurs when it rains rapidly on saturated soil or dry soil that has poor absorption ability. The runoff collects in gullies and streams and, as they join to form larger volumes, often forms a fast flowing front of water and debris.
